Engineering is different from science.
design
Design
  • The man-made world
  • The creation of artifacts
  • Adapting the environment to our needs and desires
  • Concern of engineers, architects, and artists
design as problem solving
Design as problem solving
  • Given
    • Problem specification
    • Initial conditions
    • Constraints
    • Standards/regulations
  • Find a Solution
design is creative
Design is creative
  • Design problems
    • Open-ended
    • Ill-defined (vague)
    • Multiple alternatives
    • Generate lots of solutions
design is experimental and iterative
Design is Experimental and Iterative
  • Getting it right takes many tries
  • The first cut is rarely good enough
  • Some designs fail
  • Even if satisfactory, most designs can be improved
  • Once it works, refine it
design cycle
Design cycle
  • Requirements, problem
  • Generate ideas
  • Initial concept
  • Rough design
  • Prototype
  • Detailed design
  • Redesign

Design
  • The core problem solving process of technological development
  • “It is as fundamental to technology as inquiry is to science or reading is to language arts”
serious problems in science technology engineering and math education
Serious Problems in Science, Technology, Engineering and Math Education
  • Declining enrollments in engineering programs
  • Numbers of women and minority students in engineering are not representative of general population
  • Lower science and math test scores of US high school students with respect to the rest of the industrial world
  • Technological illiteracy
vmseei
VMSEEI
  • The Virginia Middle Schools Engineering Education Initiative (VMSEEI) will design, implement, test and evaluate“engineering teaching kits” to be used by teachers and student teachers to facilitate engineering instruction in middle schools.
engineering teaching kits
Engineering Teaching Kits
  • The engineering teaching kits (ETKs) will allow teachers to instruct students on selected engineering concepts and procedures within the context of preexisting science and mathematics classes
engineering teaching kits26
Engineering Teaching Kits
  • ETKs will include a strong focus on design and innovation, how things work, how things are made, and the social and environmental impacts of technology.
  • The ETKs will involve active, hands-on, cooperative learning; students will work in teams to solve problems and design solutions.
each etk will include
Each ETK will include
  • A student guide explaining key concepts and methods
  • A teacher’s guide
  • Plans for demonstrations and experiments
  • Where appropriate a computer-based component (such as a demonstration or simulation).
some concerns
Some concerns
  • Meeting state and national standards (VA SOLs, Massachusetts, NCES, Benchmarks, ITEA)
  • Making ETKs Female Friendly
  • Incorporating ethical, environmental, aesthetic, cultural and social issues
  • Conveying the excitement and importance of engineering

HOW DOES A SOLAR CAR WORK?

HOW IT WORKS

Energy Transfer:

  • Light hits the Solar Cell.
  • Light Energy gets converted to Electrical
  • Energy (Voltage and Current) through the
  • Solar Cell.
  • The Motor converts the Electrical Energy to
  • Mechanical Energy.
  • Directly or through Gears or Pulleys the
  • Mechanical Energy drives the wheels.
slide54

THE COMPETITION – “THE WORLD’S STRONGEST MODEL SOLAR CAR”

An interesting twist on the overdone solar car drag race – Students will be asked to build a car based on power rather than speed. The winning car will be the one that pulls the most weight.
